Legislative Violence and Party System Data for Europe, 1980-2021

European legislatures from 1980 to 2021 provide the scope for this country-year panel dataset. It contains replication materials for an article on party institutionalisation, party-system closure, polarisation, and recorded physical violence. The package includes analytic data, Python code for reproducing descriptive tables, PPML models, robustness checks, and figure source data.

Use Cases

• Modeling the relationship between party institutionalisation and legislative violence based on the described variables.
• Analyzing trends in party-system closure and polarisation across European countries over time.
• Reproducing and extending the original study's PPML models using the provided Python code.
• Conducting robustness checks on the link between system closure and physical conflict in legislatures.

Strengths

• Data covers a long temporal range from 1980 to 2021.
• Replication package includes analytic data, Python code, and model specifications for full reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
